Description

Die Erfindung betrifft eine Wasserturbine und Pumpe preit stehender Welle und hydraulisch verstellbaren Laufradschaufeln.The invention relates to a water turbine and pump preit standing Shaft and hydraulically adjustable impeller blades.

Zweck der Erfindung ist, für die Lagerung der stehenden Welle einer solchen hydraulischen Maschine und für die Zu- und Abführung der zum Verstellen ihrer Laufradschaufeln benötigten Druckflüssigkeit eine Anordnung zu schaffen, die hinsichtlich Herstellung und Errichtung technische Vorteile bietet. Um dies zu erreichen, ist gemäß der Erfindung die stehende Welle in einem Axiallager und in zwei Radiallagern gelagert, von denen das Aaallager und das von diesem entferntere Radiallager auf dem Maschinendeckel abgestützt sind und das andere Radiallager in das Gehäuse des Axiallagers eingebaut ist. Ferner dient das eine dieser Radiallager als Zuführung für eine Druckflüssigkeit zum Verstellen der Laufradschaufeln in einer Verstellrichtung und das andere als Zuführung für eine Druckflüssigkeit für die andere Verstellrichtung der Laufradschaufeln. Eine solche Kombination der angeführten, an sich bekannten Merkmale ergibt bei doppelter Lagerung äer stehenden Maschinenwelle in zwei Radiallagern und ferner in einem Axiallager einen gedrungenen Block, der sich am Herstellungsort der hydraulischen Maschine vollkommen fertig zusammenbauen und alsdann an die Errichtungsstelle der hydraulischen Maschine bringen läßt, wo er ein einfaches Ausrichten dieser Maschine vor ihrem Kuppeln mit einem elektrischen Teil oder einem Getriebe gestattet.The purpose of the invention is for the storage of the standing wave a such hydraulic machine and for the supply and discharge of the adjustment their impeller blades required hydraulic fluid to create an arrangement that offers technical advantages in terms of manufacture and erection. To achieve this, is according to the invention, the standing wave in a thrust bearing and in two radial bearings stored, of which the Aaallager and the more distant radial bearing on the machine cover are supported and the other radial bearing in the housing of the Axial bearing is installed. Furthermore, one of these radial bearings serves as a feed for a hydraulic fluid to adjust the impeller blades in one adjustment direction and the other as a supply for a pressure fluid for the other adjustment direction of the impeller blades. Such a combination of the listed, known per se Characteristics results from double bearings on the standing machine shaft in two radial bearings and also in a thrust bearing a compact block that is located at the manufacturing site Assemble the hydraulic machine completely and then to the installation site the hydraulic machine, where he can easily align this machine before coupling them to an electrical part or gearbox.

In der Zeichnung ist eine beispielsweise Ausführungsform des Erfindungsgegenstandes veranschaulicht, und zwar zeigt die Figur einen axialen Längsschnitt durch einen Teil einer Kaplanturbine mit stehender Welle.The drawing shows an example embodiment of the subject matter of the invention illustrates, namely the figure shows an axial longitudinal section through a Part of a Kaplan turbine with a standing wave.

In der Figur bezeichnet i die Welle einer im übrigen nicht gezeigten, von der Kaplanturbine angetriebenen Maschine. In den meisten Fällen wird es sich dabei um eine Generatorwelle handeln, die über eine Kupplung 2 mit dem oberen Ende der hohl ausgebildeten Turbinenwelle 3 in nicht gezeigter Weise drehfest verbunden ist. Dieser Welle 3 ist ein Axiallager zugeordnet, dessen Gehäuse 13 am Maschinendeckel 21 der Turbine abgestützt ist. Am unteren Ende ist die Turbinenwelle 3 in nicht gezeigter Weise mit der Nabe 4 des Laufrades der Kaplanturbine drehfest verbunden. Im Innern der Laufradnabe 4 ist ein Verstellkolben 5 zurre Verdrehen der Laufradschaufeln 6 untergebracht. Eine Zuführung von Druckflüssigkeit, vorzugsweise Drucköl, nach einem Raum 7 oberhalb des Verstellkolbens 5 findet über eine Leitung 8, ein Radiallager 9 und in der Turbinenwelle vorgesehene Bohrungen i o statt. Das Radiallager 9 ist ebenfalls am Maschinendeckel 21 abgestützt, jedoch vom Axiallager getrennt angeordnet. Die Zuführung von Druckmitteln nach dem Raum i i unterhalb des Verstellkolbens 5 findet dagegen über eine Leitung 12, ein :mit dem Axiallagergehäuse 13 verbundenes, zusätzliches Radiallager 14, in der Welle 3 vorgesehene Öffnungen 15 sowie ein in der Welle gelagertes Rohr 16 statt. Das Rohr 16 ist mittels Zapfen 161, die durch Schlitze 17 in der Welle 3 hindurch in entsprechende Ausnehmungeh einer Verstellmuffe 18 ragen, mit einem Hebelgestänge i9, 2o verbunden, das zwecks Rückführung mit einem nicht gezeigten Steuerregler zusammenwirkt. Das rotierende Rohr 16 liegt unterhalb und oberhalb der Wellenschlitze 17 mittels Dichtungen 22 bz". 23 an der Welle 3 all.In the figure, i denotes the shaft of an otherwise not shown, machine driven by the Kaplan turbine. In most cases it will act around a generator shaft that has a coupling 2 with the upper end the hollow turbine shaft 3 rotatably connected in a manner not shown is. This shaft 3 is assigned an axial bearing, the housing 13 of which is on the machine cover 21 the turbine is supported. The turbine shaft 3 is not at the lower end in FIG The manner shown is non-rotatably connected to the hub 4 of the impeller of the Kaplan turbine. In the interior of the impeller hub 4 there is an adjusting piston 5 for rotating the impeller blades 6 housed. A supply of pressure fluid, preferably pressure oil, after a space 7 above the adjusting piston 5 takes place via a line 8, a radial bearing 9 and holes provided in the turbine shaft i o instead. The radial bearing 9 is also supported on the machine cover 21, but arranged separately from the axial bearing. The supply of pressure medium to the space i i below the adjusting piston 5 on the other hand takes place via a line 12, a: connected to the axial bearing housing 13, additional radial bearing 14, openings 15 provided in the shaft 3 and an in the shaft mounted tube 16 instead. The tube 16 is by means of pins 161, which through Slots 17 in the shaft 3 through into corresponding recesses in an adjusting sleeve 18 protrude, connected to a lever linkage i9, 2o, which for the purpose of return with a not shown cooperates control regulator. The rotating tube 16 lies below and above the shaft slots 17 by means of seals 22 or 23 on the shaft 3 Alles.
